Grand Challenges of Traceability: The Next Ten Years

In 2007, the software and systems traceability community met at the first Natural Bridge symposium on the Grand Challenges of Traceability to establish and address research goals for achieving effective, trustworthy, and ubiquitous traceability. Ten years later, in 2017, the community came together to evaluate a decade of progress towards achieving these goals. These proceedings document some of that progress. They include a series of short position papers, representing current work in the community organized across four process axes of traceability practice. The sessions covered topics from Trace Strategizing, Trace Link Creation and Evolution, Trace Link Usage, real-world applications of Traceability, and Traceability Datasets and benchmarks. Two breakout groups focused on the importance of creating and sharing traceability datasets within the research community, and discussed challenges related to the adoption of tracing techniques in industrial practice. Members of the research community are engaged in many active, ongoing, and impactful research projects. Our hope is that ten years from now we will be able to look back at a productive decade of research and claim that we have achieved the overarching Grand Challenge of Traceability, which seeks for traceability to be always present, built into the engineering process, and for it to have "effectively disappeared without a trace". We hope that others will see the potential that traceability has for empowering software and systems engineers to develop higher-quality products at increasing levels of complexity and scale, and that they will join the active community of Software and Systems traceability researchers as we move forward into the next decade of research

Extraction and parsing of herbarium specimen data: Exploring the use of the Dublin core application profile framework

Herbaria around the world house millions of plant specimens; botanists and other researchers value these resources as ingredients in biodiversity research. Even when the specimen sheets are digitized and made available online, the critical information about the specimen stored on the sheet are not in a usable (i.e., machine-processible) form. This paper describes a current research and development project that is designing and testing high-throughput workflows that combine machine- and human-processes to extract and parse the specimen label data. The primary focus of the paper is the metadata needs for the workflow and the creation of the structured metadata records describing the plant specimen. In the project, we are exploring the use of the new Dublin Core Metadata Initiative framework for application profiles. First articulated as the Singapore Framework for Dublin Core Application Profiles in 2007, the use of this framework is in its infancy. The promises of this framework for maximum interoperability and for documenting the use of metadata for maximum reusability, and for supporting metadata applications that are in conformance with Web architectural principles provide the incentive to explore and add implementation experience regarding this new framework

Entity Suggestions in Custom Audiences

A data processing system can generate associations between user interests and target users based on advertiser features to allow for specific targeting of users with content such as media or advertisements. The target users can be associated with user behaviors such as, for example, client device capabilities, user browsing behavior and actions, or a combination thereof. The advertiser features can be, for example, campaign or ad groups, landing pages, websites, or a combination thereof. The user interests can be keywords, URLs, applications, and locations, or a combination thereof. The user interests, target users, and advertiser features can each be represented by a deep neural network. The data processing system can train the deep neural network to match conversion events between target users and advertiser features through user interests. The data processing system can then retrieve embedding representations of specific campaigns based on advertiser features

Customizing DSpace Manakin for Educational Video Collections to Enhance User Experience

4th International Conference on Open RepositoriesThis presentation was part of the session : Conference PostersThe poster reports our experience of using DSpace Manakin for Starlink Video Repository. The project is a cooperation between STARLINK (Richardson, TX) and TxCDK of University of North Texas, under the supervision of Dr. William Moen. The project uses DSpace v.1.5 Manakin to create a dynamic digital repository system to store, manage and present STARLINK's various video collections. STARLINK has recently successfully launched its Ideas Collection with the new depository with much improved user interface and seamless integration with STARLINK's existing web site. More collection will be added to the depository for more streamlined operation. The project showcases DSpace as a low-cost and flexible platform appropriate for educational institution like STARLINK to run a web-based depository system for better resource sharing and user interaction. The poster will also discuss the challenges the project faced in customizing DSpace to provide different types of access for subscription and non-subscription users, and DSpace Manakinâ s better interface design functionalities.STARLIN

Biochar-amended potting medium reduces the susceptibility of rice to root-knot nematode infections

Background: Biochar is a solid coproduct of biomass pyrolysis, and soil amended with biochar has been shown to enhance the productivity of various crops and induce systemic plant resistance to fungal pathogens. The aim of this study was to explore the ability of wood biochar to induce resistance to the root-knot nematode (RKN) Meloidogyne graminicola in rice (Oryza sativa cv. Nipponbare) and examine its histochemical and molecular impact on plant defense mechanisms. Results: A 1.2 % concentration of biochar added to the potting medium of rice was found to be the most effective at reducing nematode development in rice roots, whereas direct toxic effects of biochar exudates on nematode viability, infectivity or development were not observed. The increased plant resistance was associated with biochar-primed H2O2 accumulation as well as with the transcriptional enhancement of genes involved in the ethylene (ET) signaling pathway. The increased susceptibility of the Ein2b-RNAi line, which is deficient in ET signaling, further confirmed that biochar-induced priming acts at least partly through ET signaling. Conclusion: These results suggest that biochar amendments protect rice plants challenged by nematodes. This priming effect partially depends on the ET signaling pathway and enhanced H2O2 accumulation
